If I have a component that is rendered by an ActionEvent, how to I keep the component rendered on the page if I rerun the even?

[Todd Patrick <To...@dtn.com>]

I have the following tree2 (that is working... horray!) that is
displayed based on a call to an ActionEvent:
 
<t:tree2
id="clientTree"
value="#{tbrowser.treeData}"
var="node"
varNodeToggler="t"
showRootNode="false"
rendered="#{tbrowser.displaytree}">
 
In my backing bean, I have the following code defined:
 
private boolean displaytree;
 
public boolean isDisplaytree() {
    return displaytree;
}
    
public void setDisplaytree(boolean _displaytree) {
    this.displaytree = _displaytree;
}
 
public void transTypeSelected(ActionEvent event) {
...
    this.displaytree = !this.displaytree;
    FacesContext.getCurrentInstance().renderResponse();
}
 
When I click on the h:commandButton:
 
<h:commandButton value="Search"
actionListener="#{tbrowser.transTypeSelected}"/>
 
Everything displays as I expected.
 
The second time I click on the h:commandButton, I return an error
"java.lang.IllegalArgumentException: Unable to locate facet with the
name: index"; which basically breaks my TreeNodeBase:
 
TreeNode treeData = new TreeNodeBase("index", "Transactions", false);
 
I believe that after I set the displaytree value (rendered) to true then
back to false, my Java tree code can't find the tree2 component.
 
Thoughts on how to fix this, do I just refresh the tree? How do I
accomplish that?
 
Thanks,

just a quick guess:

-try to remove the renderResponse()
-use immidate="true" on the commandButton, which is invoking your actionListener
